Sterling Silver genuine Dioptase in matrix adjustable ring. Super rare. Currently sized to a 9 so that you can see the part where the ring adjusts. I would not recommend going above a size 9 unless you want the sizing part to show a gap. Hallmarks: 925 Excellent condition but please review the photos carefully for any possible signs of wear from handling and/or storage. Originally purchased from Enchanting Earth. Pictures are enlarged to show detail please refer to the photos with measurements for true approximate dimensions. Colors may vary by monitor and lighting.
